In the biosynthesis of fatty acids from 1-(14)C-acetate by intact spinach chloroplasts, ATP and Triton X-100 exert opposing effects on the conversion of palmitic acid to stearic acid; thus, ATP decreases the conversion and Triton X-100 increases the conversion. Changes in the availability of photosynthetically generated reduced nicotinamide adenine dinucleotide phosphate apparently does not markedly affect the C(16)-C(18) ratio. Various H(2)O(2)-generating systems, such as viologen dyes, inhibit oleate synthesis from acetate and cause stearate to accumulate. Catalase partially reverses the effect of these days.
